Can only speak for myself here, but I doubt I'm alone. Sex is best with someone you aren't in love with. Once you love them, it's tough to objectify them.
Unless one or both partners are very creative and their kinks line up, most of the time the sex in the relationship will wane and the relationship will end. In my view, it's unnecessary to walk away from love as long as an open relationship is an option. Sadly, most gay men nowadays take too many queues from straight relationships where there are children involved. This is doubly sad because there are so few gay people in the general population that your odds of finding deep abiding love more than once or twice in your lifetime are quite low. When you find it and you love the person, you should work it out. A loving, but sexless, relationship is not the end of the world. In my view, it's preferred because (at least in my case) it's a reflection of my inability to objectify the person.
Decry this all you want, but the reality is that most gay men lose their virginity in the woods or in a mall bathroom; not in a hotel room after senior prom. A huge percentage of gay men like me are simply not wired for romantic sex with a life partner, but that doesn't mean that we aren't capable of giving, and don't want, love.
I don't think this holds water.
People are expected to have fantastic sex lives ALL the time! Aren't you??! Why not??!! ...and so on. Part of this is the media, and I include TV and lifestyle magazines in that setting unrealistic ideas in people's heads. Same as health and fitness regimes or beauty magazines. Chances are you're not like that, and indulging in that will just make you feel fat and/or ugly... same with sex talk - you'll end up feeling like a born-again virgin.
Does everyone really have a totally satisfying sex life with smash hit after smash hit every time? Really?*
It is possible to grow and sustain a relationship
with great sex. Trust me. But you both have to work at it.
Also, I'm not sure that most gay men lose their virginity in the woods or in a toilet. Again, the internet makes it much simpler and I daresay many young men shag for the first time in some friend's bedroom, as they always have. It needn't be some insalubrious fantasy.
Another addendum to all this is FOMO. This is true for both(all?) sexes and sexualities and this is a comparatively new phenomenon is a Gen X/Millennial affliction. Before this time/before the internet, people met in pubs and bars, got drunk, hoped to find someone who wasn't utterly repulsed by them and maybe get it on. Remember all that?
In today's competitive dating market, people tend towards the, "There could be something even better round the corner" and are less likely to commit early and (because of what I've sketched out above) have much higher standards/expectations.
People want more, expect more.
Not sure if they get more but then I don't have to do the dating thing, so.
* I mostly do, but I tend to skew most surveys and should not be taken as "normal".
